For us, the email signature is a channel in its own right, just like our social networks. It is subject to thoughtful planning with regard to our brand and business. Letsignit's scheduling feature allows us to manage it in a productive and efficient way.

It is a tool that is both simple and powerful for standardizing employees' email signatures. Additionally, it treats the signature as a new media and can be used as a low-cost acquisition channel. All of this is integrated into Microsoft Office 365.

Carole Benichou

Director of Microsoft 365 Division

We have internal support that receives fewer requests because we are better equipped to handle email signature issues. More importantly, we consistently promote the brand using the same visuals, while ensuring the integrity of the company's overall communication.

Jean-Philippe Henry

CIO

It strikes a great balance between being flexible and easy for people to use, without requiring any HTML or design skills. The support team has been very helpful, and new features are released regularly. The software has been very stable.

How does Letsignit support Green IT initiatives?

Every email has a carbon footprint, and non-optimized email signatures increase it unnecessarily. Oversized images, poor formatting, and heavy HTML significantly increase email weight… multiplied by thousands of employees, every day.

As a responsible technology provider, Letsignit is designed to reduce the environmental impact of business communications.

We contribute in several ways:

Lightweight signature architecture
Optimized HTML structure and compressed assets to minimize email size without compromising brand consistency.
Performance-optimized hosting & infrastructure
Efficient architecture designed to reduce resource consumption.
Smart usage features
A built-in “Switch to Teams” widget encourages employees to move ongoing conversations to chat instead of generating long email threads.
Alignment with CSR and ESG commitments
Letsignit supports organizations looking to align digital communication practices with their sustainability goals.

By combining brand governance with responsible digital practices, Letsignit helps companies reduce unnecessary digital pollution — at scale.
